A system for nucleic acid amplification is to synthesize amplified target nucleic acids or determine the presence of target nucleic acid. The mobile device of the system may be implemented with software for analyzing the reaction or optionally delivering the information of a sample to a cloud. Therefore, the system can provide corresponding genetic information of organism, cancer cells or viruses of interest. The information may include gene expression levels of interest, DNA identity of samples as well as treatment suggestion and professional lists for consulting. The system could also optionally be used with a mobile device to amplify the target nucleic acid for the downstream sequencing or measurement.

The present invention contemplates use of encapsulated aqueous and non-aqueous reagents, solutions and solvents and their use in laboratory procedures. These encapsulated aqueous or non-aqueous reagents, solutions and solvents can be completely contained or encapsulated in microcapsules or nanocapsules that can be added to an aqueous or non-aqueous carrier solution or liquid required for medical and research laboratory testing of biological or non-biological specimens.

The disclosure relates to a microfluidic control chip. The microfluidic control chip may include an upper cover, a lower cover, and a chip functional layer between the upper cover and the lower cover. The chip functional layer may include a first region. The chip functional layer in the first region may include at least one chamber unit, an inlet flow channel to the chamber unit, and an outlet flow channel from the chamber unit. The chamber unit may include a main flow channel, a plurality of secondary flow channels, and a plurality of microcavity structures. The chamber unit may be configured to allow a liquid to flow from the main flow channel to the plurality of secondary flow channels, and then to the plurality of microcavity structures.

A microfluidic device is for processing and aliquoting a sample liquid. The microfluidic device has a dividing chamber for receiving a starting volume of the sample liquid. The dividing chamber has a plurality of cavities for receiving sub-volumes of the sample liquid, the sub-volumes being usable for analytical reactions. The microfluidic device also has a microfluidic network for using the dividing chamber in a fluid-mechanical manner and at least one pump device for pumping fluids within the device. The at least one pump device and the microfluidic network are configured to pump the sample liquid, as a first phase, and a sealing liquid, as a second phase, through the microfluidic network and into the dividing chamber in order to seal the sub-volumes of the sample liquid in the cavities using the sealing liquid.

The invention provides a version of fluorescent in situ hybridization (FISH) in which all the steps are performed at physiological temperatures, i.e., body temperature, to detect and identify pathogenic bacteria in clinical samples. Methods of the invention use species-specific fluorescent probes to label clinically important infectious bacteria. A sample such as a urine sample is loaded into a cartridge, fluorescently labeled, and imaged with a microscope. Labelled bacteria are pulled down onto an imaging surface and a dye cushion is used to keep unbound probes off of the imaging surface. A microscopic image of the surface shows whether and in what quantities the infectious bacteria are present in the clinical sample.

Flow cell devices, cartridges, and systems are described that provide reduced manufacturing complexity, lowered consumable costs, and flexible system throughput for nucleic acid sequencing and other chemical or biological analysis applications. The flow cell device can include a capillary flow cell device or a microfluidic flow cell device.

The invention provides integrated Organ-on-Chip microphysiological systems representations of living Organs and support structures for such microphysiological systems.

A thermal cycling device comprising a number of fixed thermal zones and a fixed conduit passing through the thermal zones. A controller maintains each thermal zone including its section of conduit at a constant temperature. A series of droplets flows through the conduit so that each droplet is thermally cycled, and a detection system detects fluorescence from droplets at all of the thermal cycles. The conduit is in a single plane, and so a number of thermal cycling devices may be arranged together to achieve parallelism. The flow conduit comprises a channel and a capillary tube inserted into the channel. The detection system may perform scans along a direction to detect radiation from a plurality of cycles in a pass.
